The invention relates to a method for producing a sandwich structure having two steel face sheets separated by a polymer layer, said method comprising the following steps: - the sandwich structure is sized according to an objective to be achieved, by carrying out the following sub-steps: - the objective to be achieved is defined in terms of three target values, that is to say tensile stiffness Tc, expressed in kN/mm, bending stiffness Bc, expressed in kN/mm, and mass per unit area Mc, expressed in Kg/m2; - a tolerance margin for achieving the target values is defined; - the sandwich structure is defined in terms of five variables, that is to say the thickness Ea of the steel face sheets, expressed in mm, the thickness Ep of the polymer layer, expressed in mm, the intrinsic Young's modulus Yp of the polymer layer, the intrinsic density dp of the polymer layer, and the volume fraction Rp of the polymer layer, expressed as volume percent of the material polymer layer; - the combinations of Ea, Ep, Yp, dp and Rp that make it possible to achieve the target values within the defined tolerance margin are defined; - or every variable a useful range is determined from the above; - the steel and polymer layer are selected for which every variable is situated in the range defined in the previous step; - and the corresponding sandwich structure is produced. |
